It looks like you have run into a bug we are currently sorting out. In the mean time, we have a fix that you can use. It involves editing the source files for the Instagram plugin. Here is what you can do:
1) Go to the "Plugins" menu item in your dashboard
2) Scroll down to "Instagram Feed Pro" and select "Edit".
3) On the right hand side you'll see a blue link to the file "instagram-feed-pro/js/sb-instagram.js". Click on it.
4) Scroll down to lines 1213 and 1214 (or near the end of the file since there are no line numbers) and change them from
}, 500);
} // End carousel
to
}, 2000);
} // End carousel
See the screenshot for help with this.
Let me know if you need any more help with this!
